Note that this approach will work with any backend map server that supports the OGC WPS specification. The result from this request would be a WKT encoding of a polygon that is the 50m buffer of the input polyline. Add feature to map and do any other processing.

Capture buffer distance from user input.Capture polyline from user input (as WKT or GML).The output from the process is the generated buffer geometry and that can be requested in a number of formats, all of which can be read by OpenLayers. Quadrant Segments: Effectively the quality of the generated buffer.Distance: Specified in the same units as the geometry.Input Geometry: In a range of formats such as WKT, GML.The JTS:buffer process takes the following parameters: In my opinion the JTS:buffer process is most like what you have mocked up using MapInfo. The default installation of GeoServer's WPS extension contains a number of different processes that can be run including several for buffering: If you have access to GeoServer then you can achieve what you need through the WPS extension of GeoServer ( Web Processing Service). There is an example of doing a buffer operation with OpenLayers which you could adapt to your own needs. There is a pure JavaScript port of the Java Topology Suite called JSTS which contains (amongst many other things) a buffer operation. The approach you take will depend on whether you want the processing overhead on the client or on the server (or even if you have access to a backend server like GeoServer). However, always be sure to read the TE buffer safety data sheet before use.There are 2 ways you could approach this server side or client side. TE buffer is not classified as hazardous. Store TE buffer at room temperature (+15 oC – +25 oC). To sterilise, autoclave the solution on a liquid cycle (20 min at 15 psi).Place the lid on the bottle and invert a few times to mix.Top up the solution to 100 mL by adding 98.8 mL of distilled water.Measure out 0.2 mL 0.5M EDTA (pH 8.0) and add to the Duran bottle.Measure out 1 mL 1M Tris-Cl (pH 8.0) and add to a 100 mL Duran bottle.The recipe below is to create a 100 mL TE buffer solution.

The Tris solution keeps the DNA soluble in water while EDTA, a chelator of cations such as magnesium, protects nucleic acids against enzymatic degradation. TE buffer (Tris-EDTA) is a commonly used buffer solution for resuspending and storing nucleic acids, especially DNA.
